WINDOW GRATING Filed Aug- 2 7, 1954 2 Sheets-Shect 2 BY h. ATTORNEY Patented Oct. 1, 1935 UNITED STATES PATENT OFFIQE Application August 27,

Claims.

This invenion relates to window gratings for use in preventing would-be intruders from entering through windows or other openings, and pertains more particularly to improvements in the type of window grating disclosed in my Patent No. 1,966,636 granted July 1'7, 1934.

It frequently happens that persons occupying a home or other building may wish to leave the windows open but hesitate to do so` for fear that an intruder will enter through the open window. To prevent such unauthorized entry either when a window is left open or is forced open by the would-be intruder, the grating of the above mentioned patent` is providedwith sliding bars that may be readily locked in the window barring po-` sition when their protection is desired and moved to. an inactive or stored position at the sides of the window when their protection is not desired.

The present invention relates to window gratings in which the bars may be readily moved to and from the window barring position as in said patent, but contemplates as one feature of the invention an improved arrangement whereby the means for slidably supporting the lower ends of the window bars and for locking these bars in the window barring position may be mounted below the sill board of the window sill where they are out of the way and partly concealed.

Another feature of the invention resides in the means for slidably supporting the window bars and for locking them in the window barring position.

A further feature resides in a guard construction whereby a person within a room may operate the bar locking means but a person outside the window is prevented by the guard from reaching in between the bars and up under the guard far enough to operate the bar releasing means.

Other features of the invention and novel combination of parts in addition to the above will be hereinafter described in connection with the accompanying drawings which illustrate good practical forrns of the invention.

Fig. 13 is a sectional View taken on the line I3,-I3 of Fig. 12.

The window grating of -the present invention may be used in connection with windows of the ordinary home or other building or in connection with other opening, and may be readily installed upon windows of various shapes and sizes. The window frame shown, which may be of the usual construction, has the sides I0, top portion II, and sill o-r bottom portion l2 and the sill is provided with the usual sill board I3 that projects into the room slightly beyond the portion I4 of the window. In the window frame are slidably mounted the upper sash I5 and lower sash I6.

The window grating of the present invention is formed `of the grating bars Il that are supported for sliding movement from the window barring position of Fig. 1 to` their inactive or stored position of Fig. 2. These bars in the construction shown have laterally bent portions adjacent their ends to which the heads I8 and I9 are secured, and each bar I'I is provided near its lower end with a bowed or approximately U-shaped portion 20 formed to clear and project inwardly under 40 the sill board I3.

The upper ends of the bars I 'I are slidably supported, in the construction shown, by the channel guide rail 2| and the lower ends of these bars are slidably supported by the channel guide rail 22 and each of these rails is provided with a laterally facing slot 23` adapted to slidably receive the laterally extending end portion or a bar I1.

These channel rails are constructed to embrace and slidably receive the bar heads, and the upper guide rail 2l in the construction shown is secured to the top portion of the window frame by screws 24 while the lower guide rail is similarly secured to the lower portion of the window bep, notch 25.

neath the sill board |3 where it is out of the way and partially concealed. t Y

It is important that means be provided for fastening the bars in spaced relation to each other along the rails in the window barring position and this is accomplished in the construction shown by forming the bar receiving notches 25 in the lower edge of the slotted portion 23V of each guide rail 2| and 22. The arrangement is such that the bars I1 may be slid along the rails 2| and 22 until they drop in the proper notches 25. The bars are locked in these notches in the construction shown by providing the lower guide rail 22 with th'e` locking strip 26 slidably mounted in the channeled portion of the rail above the slot 23.

This strip 26 is adapted to be moved to and from a position in which it rests upon the heads Q having Vthe latch 30 adapted to engage the cooperatingrshouldered portion 3| formed at an end of the strip 26. The arrangement is such that as the strip is moved to the position of Fig. 5 the -latchV 30 will snap into engagement with the portion 3| to lock the strip in this position. ,Movement of the strip 26 may be effected by a pin 32 projecting from the strip 26 through an inclined slot 33 in the front face of the rail 22. Y

It will be apparent from the foregoing that when Tthe protection of the bars I1 is .desired they are 40 moved along thestrips 2| and 22 to the window barring position as shown in Fig. 1 and are locked in this position by the strip 26 to thereby retain each bar seated-in an upper and lower When the protection of the bars is no longer desired the strip 26 is unlocked and raised whereupon the bars |1 maybe lifted out or' the notches 25 and slid along the guide rails Vto an inactive position at a side of the window as shown in Fig. 2, and since the lower bar supporting rail 22 is beneath the sillrboard |3 it is out of the walr and does not interfere with the usual use of the window sill.

Y In the modified construction of Fig. 8 the lower channel guide rail 22 is provided withV the antifriction rollers 34 secured in the lower portion or the. channel rail by the pins 35 so that the bar heads i9 will ride upon these rollers Vin moving from one notch 25 -to the other and travel 'more easily. along the rail. l

Insome cases it may be desirable to provide means other. than the key controlled lock .of Fig. 5 to secure thegrating bars in place, and Figs..9, 10 and 11 show a modified construction in which the means for shifting the locking strip 26-and hold- 65V ing it in the lockedpositionis accessible to a person in Va room but can not be reached by'a person at the outside of the window and reaching in between the grating bars. In this modied p constructionthe bar .26 is-operated by a'pin 36 70' projecting Vdownwardly vthro-ugh a slot 31 inthe lowerV wall of thechannel rail, and .access to the pin by a person A outside the window is prevented by Va Yguard 36 whichfextends downwardly from the rail 272er sill board |3 far enough to prevent a personfrom reaching in between the bars and .window are concealed by the housings 43.

up under the guard'38. The ends of this guard may be closed along its vertical edges by the inwardly turned portions 39 and the guard may be further anchored in place by the pinsV 4U. The locking strip 26 may be further held in its bar 5 locking position by the pivoted stop 4| pivotedl to the lower wall of the rail 22 by the pin 42 andi adapted to be swung to and from a position in' which it blocks the sliding movement of the pin 36. l0 In Fig. 12 a construction is shown in which the grating bars Il when moved to the sides of the These housings may be formed of sheet metal and secured to an outer edge of the side frames IU to 15 extend over the bars 'l when in their stored posi'-4 tion, and the bars may be held in this stored position by a spring clip 43 positioned near the entrance to the housing 43 as shown in Fig. 13.

Y AShould it be desired toy connect the bars |l to facilitate their movement to and from the window` Y' barring position, the bars maybe provided with the connecting links `41| pivoted to each other at [$5V and to the barsfat 46, and these links may also serve to strengthen or brace the bars between their ends.

When desired the bar supporting rails 2| and 22 may be sunk ush with the surface of the wood of the window frame. While the window grating has been herein described as secured to a Window frame, it may be attached to other structures or a special frame adjacent a window, door or other opening where the protection of the grating bars is desired. The channel rails 2| and 22 are preferably closed at their ends to limit the movement of the bars I1 therein, and small Vopenings may be provided in the lower portion of each guide rail through which dirt or water may escape.
